Weigh the dry rice
Measure the uncooked rice before water is added. Enter that number in grams, ounces, or pounds. If you are tracking nutrition from a dry-rice label, this starting weight should match the form of the food listed on that label.

01 / WHAT IT DOES
What the Raw to Cooked Rice Weight Converter actually calculates
The Raw to Cooked Rice Weight Converter estimates how much a known dry rice weight may weigh after cooking. Rice absorbs water, so the cooked mass is usually greater than the dry mass even though the dry rice itself has not magically gained extra calories.
This distinction matters when your food label, recipe database, or tracking app lists rice in one state while you weigh it in another. If you log a dry entry but put cooked rice on the scale, you need a consistent way to connect those two measurements. The Raw to Cooked Rice Weight Converter gives you that connection through a simple yield factor.
THE CORE FORMULACooked rice weight = raw rice weight × cooking-yield factorBatch yield factor = measured cooked batch weight ÷ measured raw batch weightA factor of 2.50 means 100 g of dry rice is estimated to become 250 g cooked. It does not mean every rice variety or cooking method will produce that exact result.
The best factor is the one measured from your own repeatable cooking process. A reference value is useful for planning, but pot size, rinsing, soaking, rice variety, water ratio, cooking time, resting time, draining, and evaporation can all change the final mass. The Raw to Cooked Rice Weight Converter therefore lets you edit the factor instead of hiding a fixed assumption.
If you are building a meal-prep workflow, pair this page with the Meal Prep Portion Calculator. For recipes that contain rice plus other ingredients, the Recipe Calories per Serving Calculator and Recipe Protein per Serving Calculator can help divide the whole recipe into consistent servings.
02 / 3 EASY POWERFUL STEPS
Use the Raw to Cooked Rice Weight Converter in 3 steps
The SEO title promises three steps; these are the three actions needed to produce and apply the estimate.
Choose or measure the factor
Start with a reference factor only when you do not have batch data. For better repeatability, cook a normal batch, weigh the finished rice, then divide cooked weight by raw weight. Enter that measured factor in the Raw to Cooked Rice Weight Converter.
Use the cooked result
Read the estimated cooked weight and, if helpful, the cooked weight per portion. You can then weigh servings from the finished pot while keeping your nutrition calculation tied to the original dry amount.
03 / METHOD
Raw to Cooked Rice Weight Converter formula and assumptions
The math is deliberately simple: multiply raw mass by a yield factor. The important part is not the multiplication; it is choosing a factor that matches the rice and cooking method you actually use.
Why the cooked weight changes
Cooking rice mainly changes its water content. Water absorbed into the grain increases the total weight, while evaporation or draining changes how much water remains in the finished batch. That is why two cooks can begin with the same dry weight and finish with different cooked weights.
The Raw to Cooked Rice Weight Converter does not estimate calories, carbohydrate grams, or protein by adding nutrition to the rice. It only changes the weight estimate between dry and cooked states. For nutrient tracking, use the nutrient values that correspond to the food state you are logging, and avoid mixing a dry nutrition entry with an unadjusted cooked scale weight.
How to calculate your own factor
Suppose you weigh 300 g of dry rice, cook it the way you normally do, and weigh 765 g after cooking and resting. Your batch factor is 765 ÷ 300 = 2.55. Enter 2.55 into the Raw to Cooked Rice Weight Converter the next time you want to estimate cooked weight from the same dry preparation.
If your next batch produces 738 g from the same 300 g dry amount, that factor is 2.46. The difference is useful information rather than a calculator failure. It shows that your real kitchen process varies. For meal prep, you can either use the actual batch weight each time or use an average factor from several consistent batches.
04 / YIELD FACTORS
Reference factors help you start; your own batch helps you repeat.
The Raw to Cooked Rice Weight Converter includes 2.32× as a white-rice reference, 2.63× as a brown-rice reference, and 2.50× as a neutral planning default. The white and brown references reflect an FAO example in which 100 g raw white rice yielded about 232 g cooked and 100 g raw brown rice yielded about 263 g cooked. These are examples, not universal kitchen guarantees.
USDA Food Buying Guide material also shows that dry-to-cooked yield differs by rice type and form. Its grain tables report different cooked-cup yields for regular long-grain, short/medium-grain, parboiled, instant, and brown rice. Because cup volume and cooked density are not interchangeable with a single weight factor, the Raw to Cooked Rice Weight Converter keeps the factor editable rather than pretending all those products behave identically.

05 / QUICK REFERENCE
What common factors mean in plain weight terms
These rows are mathematical examples. They show what the Raw to Cooked Rice Weight Converter produces when each factor is applied.
| Raw rice | 2.32× factor | 2.50× factor | 2.63× factor | How to use it |
|---|---|---|---|---|
| 50 g | 116 g cooked | 125 g cooked | 131.5 g cooked | Small single-serving planning example |
| 100 g | 232 g cooked | 250 g cooked | 263 g cooked | Easy baseline for comparing factors |
| 200 g | 464 g cooked | 500 g cooked | 526 g cooked | Small meal-prep batch |
| 500 g | 1,160 g cooked | 1,250 g cooked | 1,315 g cooked | Larger batch; weigh the actual pot for best precision |
The table is not a promise that 100 g of your rice will become one specific cooked weight. Use the Raw to Cooked Rice Weight Converter with your measured factor whenever your preparation consistently differs from the reference examples.

07 / MEAL TRACKING
Using the Raw to Cooked Rice Weight Converter for meal prep
The most reliable tracking workflow is consistent about food state. Decide whether your nutrition source is based on dry rice or cooked rice, then keep your weighing method aligned with that choice.
If a package lists nutrition for a dry serving, you can weigh the total dry amount going into the pot, calculate total nutrition from that dry amount, then weigh the finished batch. The finished batch weight tells you what fraction of the original nutrition belongs to each cooked portion. The Raw to Cooked Rice Weight Converter can estimate that finished weight before cooking, but the actual cooked batch weight is preferable when it is available.
For example, if 300 g dry rice contains the total nutrients you plan to divide across six meals and the cooked batch weighs 750 g, each 125 g cooked portion represents one-sixth of the batch. You do not need to pretend 125 g cooked has the same nutrient density as 125 g dry. You are allocating the nutrition of the original dry batch across its cooked yield.
The Nutrition Label Serving Calculator can help scale package information to the amount you use. If the rice is part of a complete dish, use the Recipe Calories per Serving Calculator. If protein distribution is the main goal, combine the finished meal plan with the Meal Protein Distribution Planner or the site’s Protein Calculator.
When the estimate is enough
The Raw to Cooked Rice Weight Converter is useful when you are planning shopping, batch size, storage containers, or rough serving weights before the rice is cooked. An assumed factor is often adequate for that job because the purpose is forecasting rather than exact retrospective tracking.
When to weigh the cooked batch instead
If you need the closest practical match for a specific batch, weigh the actual finished rice after cooking. The calculator cannot know how much water your pot retained. Use the measured cooked weight for that batch, and use the resulting factor to improve future estimates in the Raw to Cooked Rice Weight Converter.
08 / COMMON MISTAKES
Where raw-to-cooked rice conversions go wrong
Avoiding these mistakes matters more than chasing an extra decimal place.
Mixing dry nutrition with cooked weight
A 100 g dry entry and a 100 g cooked portion are not the same quantity of rice because cooking changes water content. Use the Raw to Cooked Rice Weight Converter or your measured batch yield to connect the states before assigning nutrition.
Keep the nutrition entry and weighing method consistent.
Assuming one factor fits every rice
Different rice products and cooking methods do not absorb and retain exactly the same amount of water. A factor copied from another kitchen may be useful for planning but should not be treated as a guaranteed yield.
Measure your own batch when precision matters.
Weighing at inconsistent finish points
Freshly drained rice, rested rice, refrigerated rice, and reheated rice may not weigh exactly the same because water can continue to redistribute or evaporate. Choose a consistent point for batch calibration.
Repeat the same weigh-in routine.
10 / COMMON QUESTIONS
Raw to Cooked Rice Weight Converter FAQ
Short answers for the questions that most often affect the calculation.
How much does 100 g of raw rice weigh when cooked?
It depends on the cooking-yield factor. At 2.32×, 100 g becomes an estimated 232 g; at 2.50×, it becomes 250 g; at 2.63×, it becomes 263 g. The Raw to Cooked Rice Weight Converter lets you choose the factor instead of assuming one answer fits every batch.
Is 3× always the correct raw-to-cooked rice ratio?
No. Three times the dry weight can be a convenient rule of thumb for some preparations, but actual yield varies. Use your own measured cooked batch divided by raw batch weight when you need a factor that reflects your kitchen.
Can I use the Raw to Cooked Rice Weight Converter for basmati or jasmine rice?
Yes, as a mathematical converter, provided you enter a factor that matches your preparation. The preset references are not variety-specific guarantees. For basmati, jasmine, or any other rice you cook regularly, calibrating from one or more measured batches is more useful than assuming a universal factor.
Does cooking change the total calories in the rice?
Adding absorbed water increases cooked weight but water itself adds no calories. However, preparation can involve draining, added fat, broth, or other ingredients, so track the actual recipe. The converter only estimates weight change; it does not calculate recipe calories.
Can I convert cooked rice back to a raw equivalent?
Yes mathematically: raw equivalent = cooked weight ÷ yield factor. This page is optimized for raw-to-cooked planning, so for a reverse estimate you can divide the cooked amount by the same factor you would have used in the Raw to Cooked Rice Weight Converter.
Should I weigh rice before or after cooking for macros?
Either can work if your nutrition data matches your method. Weighing dry rice is often straightforward when using package nutrition. If you portion cooked rice, connect the cooked batch to the original dry amount so you do not mix dry nutrient density with cooked scale weight.
Why did my cooked batch weigh less than the converter predicted?
Your rice may have absorbed less water, lost more water through evaporation, been drained more thoroughly, or used a different rice-to-water method. Measure the real cooked batch, calculate its factor, and use that number next time.
What is the best yield factor for the Raw to Cooked Rice Weight Converter?
The best practical factor is the one calculated from your own repeatable batch: cooked weight divided by raw weight. Reference factors are useful for planning when no batch measurement exists, but they should remain editable assumptions.
